Ripple Rock Explosion
Ripple Rock was an underwater, twin-peaked mountain in the Seymour Narrows of the Discovery Passage in British Columbia, Canada, a part of the marine trade route from Vancouver. Only 3 meters underwater at low tide, it was a deadly marine hazard which had claimed hundreds of lives. It was destroyed by a planned explosion on 05/04/1958 using 1,270 tons of explosives placed underneath the peaks by drilling vertical and horizontal shafts from Maud Island in the sound.
